School's Out and Unplugged Science Volcano's and Sound

Youpi, May 2009

Friday was the last day of school for two weeks. We've been pretty busy with end of term meetings and outings, and now we have to prepare Marie-Kate's 5th birthday and a trip to London.
We did manage to do this weeks unplugged project, thanks to Alexis's monthly magazine "Youpi". This months theme was Volcano's.

Marie-Kate carried on this experiment because it was safe and easy. She made a volcano using some flour and soda.

She made the crater with her finger

The gas from the soda pushed the flour and the soda up and out of the crater, making it overflow like in a real eruption. Once the soda (magma)had lost its gas, the lava flowed down around the sides of her volcano.



I'd recommend this magazine to anyone, it's really super for children aged 5 to 8 years old. All my children have this magazine and loved it when they were younger. If anyone wants to swap some of our Youpi's for some something similar in English, that would be great.

Experiment N°2 Sound Waves

Alexis and Gabrielle decided to experiment with sound after watching a science programme for kids on Arte.

The noise makes the air vibrate, the noise is transmitted through the air, to the plastic. The plastic vibrates and the rice dances. The children loved this one.

  1. We've done the volcano project before, using baking soda and vinegar, but we've never tried the vibrating rice project. I'll have to remember to do that sometime. I think my son would really enjoy watching dancing rice.

  2. I've never seen that way to make a volcano. It looks interesting. My son loves to ply with baking soda and vinegar to make eruptions.

  4. These look like such fun! Volcanoes always seem like such work, but this one actually seems simple enough to be doable. And I like the rice idea.
